downloaded Bitlord now my camera light is on but can't access it

Try a restart.

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Isolating an issue by using another user account

If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

The general consensus around here is:

1) Torrent apps are sketchy to begin with, and recently one carried a hidden payload. While there are a handful of legitimate torrents out there the nature of torrent sites, torrents apps and torrents themselves is a risky business that is has questionable legitimacy due to misuse.

and

2) Norton and most if not all commercial Mac Anti-Virus solutions have been found on these forums as the root cause of serious interoperability problems in OS X. While the legitimacy of Windows AV and 3rd party protection is very much a part of that platform the Mac side of this has had far less development time, far fewer developers, no cooperation from Apple and has yet to face a legitimate attack on mac because at this time there have been no Mac viruses by definition except those developed in labs that sometimes work in conjunction with Apple and often these fixes are not discussed with outside parties. The best defense against attacks right now is keep your system updated from Apple.

You are welcome.
